Treatment of Persistent Atrial Fibrillation After Rhythm Control Has Failed to Maintain Sinus Rhythm

This protocol covers persistent atrial fibrillation — AF episodes that are not self-terminating — in patients whose previous rhythm control strategy did not achieve the intended clinical goals.

Clinical scenario

Persistent AF is characterised by AF episodes which are not self-terminating. The clinical aim is maintenance of sinus rhythm and reduction of AF-related symptoms.

Previous treatment — goals not achieved

First-line rhythm control — including antiarrhythmic drug therapy, electrical cardioversion, and catheter ablation where applicable — did not achieve or sustain the required treatment goals.

Goals not reached: maintenance of sinus rhythm & reduction of AF-related symptoms

Next-step approach (partial overview)

When antiarrhythmic drug therapy has not maintained sinus rhythm, ablation-based interventions become central to the escalated strategy. Where a prior ablation has not delivered lasting results, further procedural and pharmacological pathways remain available. The complete decision pathway — including how each recurrence scenario is addressed — is set out in the full protocol.

AF episodes which are not self-terminating.
Catheter ablation is recommended in patients with paroxysmal or persistent AF resistant or intolerant to antiarrhythmic drug therapy to reduce symptoms, recurrence, and progression of AF.
Endoscopic and hybrid ablation procedures should be considered in patients with symptomatic persistent AF refractory to AAD therapy to prevent symptoms, recurrence, and progression of AF, within a shared decision-making rhythm control team of electrophysiologists and surgeons.
Repeat AF catheter ablation should be considered in patients with AF recurrence after initial catheter ablation, provided the patient's symptoms were improved after the initial PVI or after failed initial PVI, to reduce symptoms, recurrence, and progression of AF.
